IOS google maps camera not point to the marker - ios

Question

I have a view controller in a story board and i want to show a google map on it
everything went good, i got the get and i can show the map
my problem is that the camera is not pointing to the marker
here is my code
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(#"we are in the show stadium");
// Create a GMSCameraPosition that tells the map to display the
// coordinate -33.86,151.20 at zoom level 6.
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
longitude:151.20
zoom:6];
mapView_ = [GMSMapView mapWithFrame:CGRectZero camera:camera];
mapView_.myLocationEnabled = YES;
self.mynewmap = mapView_;
// Creates a marker in the center of the map.
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(-33.86, 151.20);
marker.title = #"Sydney";
marker.snippet = #"Australia";
marker.map = mapView_;
}
where mynewmapis an UIView outlet
here is what I see
the marker is on austrail but the camera not pointing to it and the marker is not on the map

Answer 1

If you are working with Storyboards, set the class of mynewmap to GMSMapView in Interface Builder.
And in viewDidLoad just add the camera, you don't need to alloc the view because it will be already allocated:
- (void)viewDidLoad
{
[super viewDidLoad];
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:-33.86
longitude:151.20
zoom:6];
self.mynewmap.camera = camera;
}
Or try not creating your view with a Zero rect.. CGRectZero... you could try with:
mapView_ = [GMSMapView mapWithFrame:self.mynewmap.frame camera:camera];

Answer 2

Your current location & (-33.86,151.20) locations are same ya not ... You have enabled userlocation mode. Please try again after comment
//mapView_.myLocationEnabled = YES;
remove this line ... Because It's also tracking userlocation. May be help full.

Answer 3

Add this line after you are done with adding marker
[mapView_ animateToLocation:marker.position];
or use
[mapView_ animateToCameraPosition:[GMSCameraPosition cameraWithLatitude:marker.position.latitude
longitude:marker.position.longitude
zoom:6.0f]];

Faced the same issue in iOS 11, instead of setting the GMSMapView from the storyboards, initialized it in the viewDidLoad method of the viewcontroller like this:
override func viewDidLoad() {
super.viewDidLoad()
// Force the view to layout to get its proper frame
self.view.setNeedsLayout()
self.view.layoutIfNeeded()
// Initialize the GMSMapView with target view's bounds
googleMapView = GMSMapView(frame: self.mapView.bounds)
// Add the GMSMapView to the map container view
self.mapView.addSubview(googleMapView)
}
